The seating of these valves is their ehiefnnd only essential function, though in this work they are aided by fluidpressure acting, through the port 0, on the udjncent ends of the rods 0 c Beneath the valves (tngrt is, on the ends to ward which they sent) are the unsentiug thrust-rods e 12, each shutting against a screwstem, 2, connected to a cop, D, which consti-- tutes the armature of a helix or coil, I), and which latter is inclosed within the hollow onnulzrr core-extension D. This gives me what is in client on electro-inegnet at each end of the chest 13, and I only prefer the form or construction shown because it gives me in hr pact form and well inclosed a. helix of consi lerable power through a short range of motion, but long enough to unseat or open the valves. The thrust-rods e and their surronndin guides may be made of brass, or otherwise constructed so as not to be effected in their action by the tubular core I), which, if used, gives to that extent a solenoid construction and action. Over the ends are the covers D.

In order the better to explain the operation of this engine, I will suppose it to be incorporated into a railway switch and signal n1)- parntus, as illustrated in Fig. 2 'll'ere the piston-stein A is connected with any desired form of switch-shifting mechanism, such that us the piston moves one wary or the other it may, through switch-bridle I], shill; the movehis rails q one way or the other. A battery, 1 or other source of electric power, may be orrenged at any convenient point for the operator, as in a cabin, C, and o, inake-nndbrenk mechanism or key may be added, as at 7/, so that either of two wires, 1 2", may be put into circuit, the other then being out of circuit. The returnseircnitmaybe mode by the ground, or preferably by the metallic conduit-pipe m, which is designed to extend to or past two or more points where power to be applied, and a wire, 20, may connect this with the other butterypolc. The wires 1 2 load each to one end of the coils l), n id for the present purposes I will assume that the wires 3 4., which are connector withthe other ends of the coils, lend to the grouml or to the pipe or. The operator then closes circuit, say through wire 2, so to excite the righthnnd 'clcctromngnet, draw down its nrnntture, give its red c a thrust to the left, unseat the righthnnd valve 3, and allow pressure to escape from nie- preaches the end of its stroke, and "w ill be h i 1 y to its sent, and the distributing-valve f be shifted so as to uncover port (6 and port c to the exhaust, and fluid-pressure ,J. ing from chamber B will actuate the piston l lo-sing the opposite circuit through Evil l will result by the some mot-ions, but in a reverse direction, in reversingpiston is.

tlon and operation would remainsubstantially the same it the cscapoporls were normally open and variations oi fluid-pressure on the valve-moving piston were efiectuated by the closing ofonc or the other by the nse of an electromagnetic current.

In Fig. 4: I her illustrated the combination in series of the engines described,wherein the wires ll and 12 of engine No. it, instead ot'going out to constitute a signaling-circuit, go to 230 the opposite poics of the league s another like engine, lie, Thcwircfi nndilil from 'magnets to conduit mor to the ground.

the latter may go to another like engine in like manner, or may lead to signal-magnets g g, one or more, so as thereby to actuate signals II/ It, in -the manner already described.

t will now be readily understood from this drawing and the previousdescription that the engine No. 1 may be used to shift one switch, the setting or shifting of which ought to precede the setting or shifting of some other switch, which latter is to be shifted by No. 2. Then,'as soon as the piston motion of No. 1 is complete and its switch has received its full throw, the circuit will be closed by one ofthe wires 11 or 12 to one or the other of the magnets of engine No. 2, whereby, in the man ner above described, another switch may be shifted and the circuit then be formed, by wires 21. or 22, through one or more signal- The number of such engines thuselectrically coupled up in series, so as to operate in succession from the same battery, may be iiicreased at pleasure, as the work to be done may require, and the same is included as a part of the present invention; but no claim is made herein relative to the combination of a signaling system or signal apparatus with the engines dcscribed,which snbjectmattcr is reserved for separate applications.
